Davidson and Job Ohio, assignors to The S n H. Kroemer, Dayton, tandard Register Company, Dayton, Ohio, a corporation of Ohio Application May 22, 1947, Serial No. 749,640 9 Claims. (01. 271-291) This invention pertains to strip feeding and imprinting apparatus, and more particularly to differential feeding mechanism for advancing superposed record strips simultaneously through step by step movements of different extent while progressively reversing one of the strips by turning its under side uppermost, and momentarily arresting both strips with prescribed areas thereof in registry at an imprinting position.

For illustrative purposes, but with no intent to unduly limit the scope or application of the invention, it is herein shown and described in association with a conventional cash register mechanism which embodies imprinting and accumulating devices controlled by a series of manually depressible keys. The present strip feeding apparatus in association with such register mechanism may be employed for check writing or listing purposes.

One of the present record strips comprises a continuous succession of series connected detachable printed forms such as checks, vouchers, utility bills, invoices, statements or analogous record sheets, advanced one form length at a time past an imprinting position, where the succeeding forms receive entries of sums or amounts and other data determined by operation of the register control keys. The other record strip is concurrently advanced through line by line spaces and simultaneously receives duplicate imprints. This detail or data strip may also be separable at longitudinally spaced intervals upon transverse division lines into individual sheets which may be subsequently collected into book form. In such event the duplicate imprints thereon are arranged in separate. groups, preceded by skip spaces of greaterextent than line spaces to accommodate headings for the separable sheets or pages.- 1

The total of succeeding amounts imprinted upon the record forms and duplicated on the detail-or data strip is progressively accumulated upon the totalizers of the register mechanism.

The detail or data strip receiving the dupli,. cate record imprints may have been previous-v ly inscribed with a succession of names, numbers, or other identifying indicia pertaining to the checks, bills or statements comprising the companion record strip, in association with which theduplicate imprints are to be effected. The

register mechanism is ordinarily designed to print downwardly upon the upturned face of the main record strip of series connected detachable printed forms, and upwardly upon the under side of the duplicate record strip. The latter is preferably inserted in the register mechanism in relation with the printing devices thereof in an inverted position, with its inscribed face downwardly to receive the successive duplicate imprints. However, means is provided for progressively reversing a longitudinal portion of the detail or data record strip as it is advanced past the imprinting position whereby one marginal portion thereof bearing the names, numbers or identifying indicia will be overturned and rendered visible through an observation opening, while the opposite marginal portion of the strip remains in downturned position to receive the duplicate imprints.

The particular cash register mechanism illustrated in association with the present strip feeding apparatus is of conventional form, and forms no part, per se, of the present invention, other than affording a convenient imprinting and totalizing apparatus for conjoint use with the present strip feeding apparatus.

In lieu of the cash register mechanism shown, the present invention may be associated with other writing or recording apparatus, check writer, addressing machine or tabulator operable upon continuous strip stationery.

The object of the invention is to improve the construction as well as the means and mode of operation of strip feeding and imprinting ape paratus, whereby it may not only be economically manufactured, but will be more efficientin use, automatic in operation, uniform in action, having relatively few operating parts, and be unlikely to get out of repair.

A further object of the invention is to provide recording and listing mechanism simultaneously operative upon differentially advanced record strips, and means for accurately .present ingdifferently spaced record receiving areas thereof simultaneously in registryat the imprinting position.

A further object of the invention is to provide strip reversing means for progressively turning the strip upside down in unison with its advancement.

A further object of the inventionis to provide a strip feeding and imprinting mechanism possessing the, advantageous. structural features, the inherent meritorious characteristics and the mode of operation herein set'forth,'or their equivalents. I v

With the above primary and other incidental objects in view as will more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features.

of construction, the parts and combinations thereof, and the mode of operation, as hereinafter described or illustrated in the accompanying drawings, or their equivalents.

Fig. 7 .is a detail view from theextreme right, on'line 1-4 of Fig. 3.

Like parts are indicated :by similar characters of reference throughout the several views.

The present embodiment of the invention comprises an attachment or supplemental mecha nism, which as shown Fig. 1 is mounted upon a conventional cash register 1.. The supplemental mechanism is actuated independently of the cash register driving means for differentially advancing record strips .2 and 3 past imprinting devices enclosed in a box-Ilikehousin'g t. The imprinting devices within the housing '4 are actuated by operation of the cash register machine under control of manually depressible keys on the front of the cash register l. The imprinting devices, which are a part of the cash register I, operate downwardly to impress indicia upon "the previously positioned form or section of the record strip '2. The imprinting devices are simultaneously operated in an upwardly direction to im press like indic'ia upon the :under side of the record strip 3. Such imprinting devices are compionent'parts of the ca'sh'register I.

'Both strips 2 and 3 are fed simultaneously in opposite directions past the imprinting position. Strip 2 is fed from right to left past the imprinting position, while theupper tally or detail strip 3 is advanced from left to right past the imprinting positon. Although being advanced simultaneously,the respective strips 2 and 3 are advanced different distances during each feeding operation.

The record strip '2 which comprises a continuous series of connected succession of detachable checks, utility bills, invoices, or analogous forms. faces upwardly over a strip guide '5 and thence beneath the printingdevice housing 4. The strip 2 is advancd independently of thede'tail strip 3, but in unison therewith by feeding mechanism contained within a housing '3 dependent beneath the strip guide 5, at 'theleft of Fig. 1.

Form strip feeding unit The form length feeding unit for advancing the record strip 2, illustrated in Fig.2, is actuated by :anelectric motor I. The circuit for the :motor 1 :is controlled by a manual switch 8 on the .side of the housing t5. Themotorcontinues tooperate until the switch ,8 is reversed. vA signal light 1'8 in the motor circuit indicates that the motor is in operation. The motor I, acting through a reduction gear train Within the housing la drives a gear pinion l0 meshing with a pinion H fast upon a shaft [2. The shaft l2 carries a drive pulley l3. Adjacent the gear pinion H the shaft 12 carries a small ratchet wheel I4. Contiguous thereto is a loose sleeve +5 having at one end thereof agear pinion re. Adjacent to the ratchet Wheel, the sleeve 15 carries a disc i1 supporting :a spring actuated pawl l8 engageable when released with the ratchet wheel M. The pivoted pawl I8 is provided with an arm 19 projecting beyond the periphery of the disc I! and engageable at the limit of rotation of the disc, with the extremity of an oscillatory lever 20, to automatically disengage the pawl from the ratchet wheel 1'8. "The sleeve 15 and disc I? carrying the pawl I8, engageable with the ratchet wheel 44, forms a one revolution driving clutch, intermittently connecting the .sleeve 55 and gear pinion It with the shaft 12. At completion of each rotation of the sleeve i5 and disc .H with the shaft, the protruding end of the arm 19 of the pawl 18 engages the end of the upstanding lever 29 to oscillate the pawl [8, against the tension of its retracting spring '22, out of engagement with the ratchet wheel 14, thus arresting the rotation of the sleeve [5 and gear 16. The gear '16 meshes with a driven gear 23 upon a transverse pin wheel shaft 2'4, which carries two concentric axially spaced pin wheels 25. The pin wheels '25 are loosely mounted on the shaft 24 and are interconnected forun'ison rotation by an intermediate coupling sleeve 26 having interlocking clutch engajgement 2'! at each end with the respectivepin wheels. The interconnected pin wheels are adjustably connected to the shaft 2 8 for unison rotation by a conventional variable coupling 28, such as commonly employed upon typewriters.

The purpose of 'thevariable coupling 2871s to enable the forms comprising the record strip 2 to be initially correctly located relative to the point of engagement of the printing devices. After adjustmentthe'variable coupling is locked to positively'interengage the'pin wheels 25 and shaft 24 :for unison rotation. The pin wheels 25 progressively engage in longitudinally spaced marginally punched feed holes 29 in the record strip 2. The'pin wheels 25 engage with the record strip 2 coincident with a pair of slotted paper guide fingers 30 of which only one appears in Fig. 1. The intermeshing gears +6 and '23 are so proportioned that one complete rotation of the gear 16 incident to engagement of the pawl It with the ratchet wheel 14 and its subsequent release by engagement of the trip arm 19 with the end of the movable lever 20, will rotate the pin wheels suffici'ently to advance the strip 2 the distance of one form, check, bill or invoice.

The recording operation is initiated by depression of one or-more 'of the cash register value keyswhic'h are effective to set up a'sumin dollars and cents and perhaps some accompanying ;indicia, to be "printed upon the strip, check, bill or invoice, and sets the mechanism .to accumulate the sum upon the .register totalizer upon subsequent operation of the register mechanism. The actual imprinting operation is then effected byactuation of one of the operation detennining keys which effects operation of the imprinting devices within the housing 4 to imprint the amount at apredetermined position on the advanced form, check or bill, and also on the detail strip 3. .It also efiects simultaneously accumulation of such amounts upon the register totalizer. These are the normal intended functions of the cash register mechanism. In addition thereto the cash register key is especially adapted when depressed to close through the cash register mechanism an electric circuit lc which energizes a solenoid 3|, the reciprocatory core of which is connected with the lower end of the oscillatory stop lever 29 pivoted at 33 to retract the lower end of the lever 20 against the resistance of its spring 34. By such movement the upper end of the lever 20 is withdrawn from beneath the protruding arm IQ of the springpawl [8 to enable its engagement with the ratchet wheel M for one complete rotation of the shaft [2, gear I6 and disc I! carried thereby. At the limit of such rotation the pawl is again automatically disengaged by contact with the end of the pawl arm IS with the stop lever 20. Thereupon the advancement of the record strip 2 ceases until a cash register key lb is again depressed.

Detail strip feeding unit The superposed data strip 3 is advanced in unison with the advancement to the strip 2 of forms, but through much shorter distances. The strip 3 is advanced through successive line spaces whereas the strip 2 is advanced a form length at each operation. The lengths of the forms may vary and the feeding means mustbe correspondingly changed, by interchange of gear elements of different sizes.

- The detail or data strip 3 is advanced over the strip guide 34, at the left of Fig. 1, face side downwardly. The detail or data strip 3 has been previously passed through an addressing machine, a. typewriter or other imprinting apparatus by which a series of names to whom the forms, checks, bills or other records comprising the strip 2 pertain, or the list bears a succession of identifying indicia in association with which an amount agreeing with that imprinted on the corresponding form of strip 2 is to be imprinted. As before stated the cash register imprinting devices are such that while the imprinting of the forms of strip ,2 is effected downwardly on the upturned face of strip 2, other printing devices of the cash register are operative upwardly against the downturned portion of the face of the detail or data strip 3. Such oppositely directed imprint operation is a peculiarity of the instant cash register mechanism. Other embodiments of printing devices may be substituted therefor. It is desirable however that the operator be able to definitely ascertain the name of the particular person whose form, check, bill or the like is being concurrently imprinted. The previously imposed identification imprints, being on the under side of the record strip3 as it is advanced from its source of supply, at the left of Fig. 1, the record strip 3 is partially folded over in a diagonal form, enabling the identification imprints to become visible upon the overturned portion, and the record strip is progressively advanced in such position. In overfolding the mar: gin of the strip bearing the identification imprints, it is turned over a guide block 35, which also serves as a platen for the upwardly directed imprinting devices against the portion, of the record strip extending over the housing 4 and beneath the platen block 35. By continuing the advancement of the strip 3 with the overturned margin fed progressively diagonally, and while the opposite or under margin is fed in a straight path-the strip is eventually entirely overturned face upwardly.

The detail or data strip feeding mechanism is illustrated in Fig. 3. The feeding unit is driven by a belt 36, from the pulley l3 of the form strip feeding unit, Fig. 2. The drive belt 33 engages a pulley 31 upon a shaft 38. Loosely mounted on the shaft 38 is a sleeve 39 which carries a gear pinion 40 having a segment of increased thickness or width of face 4| and in spaced axial alignment therewith a cam 42. The sleeve 39 with the .gear 40 and cam 42 are detachably engageable with the shaft 38 by a single revolution clutch mechanism of the same construction before described, which is illustrated in Fig. 5. That is to say, the shaft 38 carries fast to it a ratchet wheel I4. Adjacent to the ratchet wheel I4 a disc I! is attached to the sleeve 39. To the disc I! is pivoted a spring actuated pawl l8 engageable with the ratchet wheel [4. The engagement of the pawl I8 is effective to temporarily connect the sleeve 39 together with the gear pinion 49 and cam 42 for unison rotation with the shaft 38. An arm I 9 integral with the pawl l8 protrudes beyond the periphery of the disc I1. At the completion of each rotation of the sleeve 39 and gear 40 and cam 42, in unison with the shaft 38, the arm I9 engages with the extremity of an oscillatory lever 43, which corresponds to the lever 20 of the form strip feeding unit, Fig. 2. Engagement of the arm IS with the lever 43 automatically disengages the pawl Hi from the ratchet wheel I 4 against the tension of its retracting spring 22. To initiate the advance of the detail or data strip 3, the lever 43 is automatically withdrawn by energization of a solenoid 44 to retract the lower end of the lever 43 against the yielding resistance of its spring '45. An electrical circuit is closed to energize the solenoid to initiate the feeding operation by manipulation of one or another of the keys lbof the cash register, after the predetermined amount or indicia to be imprinted has been set up. The cash register is thereby operated to imprint the selected amount and accumulate the same on the totalizer of the machine. The register key for energizing the solenoid 44 to cause'advancement of the detail record strip is the same key lb operated to effect the imprinting and advancement of the form strip 2 as previously described. In fact the initiation of operation of both strip feeding units occurs simultaneously as a single operation. The imprints upon the detail or data strip 3 are effected in successive groups at line space intervals with a wider heading space skip between.

The gear pinion 40 upon the revoluble sleeve 39 having the laterally extended integral gear segment 4| meshes with a gear wheel 46 also having a laterally extended integral gear segment 41. The peripheral face of the latter is equal to the extent of the entire peripheral face of the gear pinion 40. The gear 46 is the initial member of a gear train intermittently driving the strip feeding devices to advance the strip through step by step line spacing movements, including one step of longer duration to compensate for the heading space of each group of linespacers.

such increased advancement compensates for the form heading. The continuous face of the gear pinion 40 is positioned in laterally offset relation with the main continuous face of the gear 46. The lateral extension 41 of the gear 46 is equal to the peripheral extent of the gear pinion 40. Thus at each actuation of the sleeve 39 and gear pinion 40 while the latter-is in mesh with extem ion'll, gear :18 "is driven throughout the full rotation of the pinion 40 to actuate the strip ieeding :devices "through the danger step. During other rotations of the gear wherein the lateral extension 4-! of the gear pinion is in mesh with the main peripheral iface :of the driven gear 46, the latter :gear is ad-- vanced ithrough only short steps corresponding to line space advancements of the "feeding devices, and the main continuous body of the gearpinion tmyels idly past the gear 46 in a laterally offset path.

@onnected with the gear 46 and 'revoluble in unison itherewith is a peripherally notched disc IS, the uniformly spaced notches "49 of which 1 Successively engageablew-ith the notches 49 of Jthe disc i8 is oscillatory locking pawl or detent arm 51, which is raised by the rotary cam 2 at each rotation of the sleeve 39 to lock the mechanism at the end of each advancing movement of the feeding mechanism and holds it i stationary during the imprinting eperation.

mnnected to the gear '46 at its side opposite the notched disc 8 for "unison *rotation is a gear wheel 52 which drives through idler pinions 53 and 51,9. gear pinion 55 on a -pin wheel shaft 66. The :shaft 56 loosely carries two axially spaced pin wheels 5 and 58 which are inter-coupled with each other and "with a ifurther gear pinion 55 by intermediate coupling sleeves ill and 6 l. The pin wheels 5 and 58 and coupling sleeves 150 and BI and the gear pinion 59 are *ad'justably engageable with the :pin wheel drive shaft -55 by a conventional variable coupling 62 whichis accessible at the tront of the apparatus. By this means the pin wheels may be *revdlublyadiusted to and fro relative to the =driving mechanism toregister particular areas of the record stri with the imprinting "iDhe pin wheels 5'! and 58 are engageable in marginally punched holes *in opposite margins of a supplemental record strip (not shown) to progressively advance the strip 'inthe usual manner without reversal. Suc'h supplemental record strip is necessary ifor the recording of certaintypes of business transactions, hence means are provided for the advancement of such supplemental strip in synchronism with the advancement of strips 2 and However, to advance the record strip 3 with one margin overturned an as'kew pin wheel 63 engages the overturned punched margin, as is illus'tratedin Fig. '4,wh'ile thepin wheel 5'! engages the other punched margin thereof.

The 'askew :pin wheel -63 is mounted on a diagona'l shaft 64, having therein a universal joint 155. The gear pinion 59 upon the revolu'ble con-- pli-ng sleeve 61 drives through an idler pinion G6, a "gear pinion 61 on the universally jointed "shaft E4 to drive the askew pin wheel in unison with the pin wheel 51. Theaskew pinwheel '63 is '-revo ubly adjustable by means of the variable 6-2, in unison the :pin wheels 51 and -58.

Mountedon the universal shaft 64 and meshing with the pin wheel shaft drive pinion *55, is a toothed counter wheel 68 bearing indicia identifying the line spaces as they are advanced to and past the imprinting position.

The detail or data strip feeding mechanism, illustrated-in Fig. 3 ismountedbeneaththe continuing record strip guide at the right of Fig. 1

with the driving mechanism in dependent position'there behind. The zpositionsof the pin wheel 58 and cashew pin wheel 63 andthe variable .coupling .62 on the .extremity'o'f the pin wheel shaft '56 are visible at the right of Fig. 1. Oloselydbeside the varialzile coupling 62, Figs. 1 and '7, is shown a push button 69, in the electrical control circuit of the solenoid '44 in multiple with the operation determining key of the cash register or recording mechanism. "By depression of the button 69 the detail strip feeding mechanism may be actuated independently of the operation of the cash register -vor other recording mechanism to advance the detail or data strip 3 into synchronism with the series connected strip of -forms 2, whereby corresponding areas may be positioned in printing position in starting operations.
